[PATCH] Remove dead code in netstat from route.c

[Garrett Cooper]

Hi,
    While trying to determine how to print out routes via kvm for
net-snmp, I noticed that there's a chunk of code from the 4.4 BSD Lite
days that isn't executed in netstat as NewTree is always 0. The
following patch removes that dead code and gets the FreeBSD source for
netstat more in line with NetBSD and OpenBSD's copy.
Thanks!
